Choose this if you want a firm mattress that doesn't feel austere. The dual spring system, full-size pocket springs beneath a layer of mini pocket springs, gives you responsive support with soothing pressure relief on top. Natural fibres do the temperature work here rather than foam: wool, bamboo, alpaca, cashmere and silk all wick moisture and breathe, which means hot sleepers should stay noticeably cooler than on synthetic alternatives. It's handcrafted in the UK, approved by the National Bed Federation, and comes in five sizes from UK Single to UK Super King. Yes, it's a real investment, but a 10-year guarantee and quality natural materials make the price easier to accept.
Key Features & what's inside
- Damask cover. A finely woven, durable fabric that feels soft to the touch and doesn't retain heat. It's built for long-lasting performance.
- Comfort fillings. A blend of natural wool, tencel, bamboo and alpaca fibres, which means breathable, luxurious comfort right at the surface. These natural materials help regulate temperature through the night.
- Cashmere and silk blend. Cashmere is soft, breathable and moisture-wicking, while silk adds sumptuous comfort. Together they give the sleeping surface its premium feel.
- Dual density soft white fibres. Fluffy on one side and densely packed on the other, this layer reinforces the firm feel. It's a key part of why the mattress supports without feeling harsh.
- Mini Pocket Springs. Small, individually cased springs that add comfort and gentle pressure relief. They also reduce motion transfer, so you'll feel less of a partner's movement.
- Spring Insulation layer. This supports the main springs beneath it, which means added durability over the life of the mattress.
- Pocket Springs. Individual springs encased in cloth pockets, each adapting to your movement independently. The result is personalised support distributed across every part of your body.

Who's it NOT for?
This isn't the mattress for anyone who wants a soft or medium feel. It's firm, and owner feedback mentions an adjustment period, so if you're a lightweight side sleeper you may find it presses on your shoulders and hips. Budget shoppers should also look elsewhere: from £654, it's a considered purchase.
Relyon Luxury Pashmina 2350 Pocket Mattress
View all mattresses
How firm is the Relyon Luxury Pashmina 2350 mattress?
It's described as firm, and owner reviews back that up, calling it firm but not uncomfortably hard. The natural fillings and cashmere-silk layer soften the surface feel, so it suits people who want solid support with a touch of luxury on top.
How many springs does the Relyon Pashmina 2350 have?
It has 2,350 springs in total, split across two layers: full-size pocket springs for adaptive support and a layer of mini pocket springs above for extra comfort, pressure relief and reduced motion transfer.
Does the Relyon Pashmina 2350 come with a trial?
Mattress Online lists a 100-night trial with this mattress. That's the retailer's own offer rather than a Relyon guarantee, so if you buy elsewhere, check the seller's terms before ordering.
What sizes is the Relyon Pashmina 2350 available in?
Five UK sizes: Single, Small Double, Double, King and Super King, priced from £654 to £998 depending on the size you choose. The mattress is 30cm deep across all sizes.
Is the Relyon Pashmina 2350 good for hot sleepers?
It should be. There's no memory foam here; the fillings are natural wool, tencel, bamboo, alpaca, cashmere and silk, all of which breathe and wick moisture. The damask cover doesn't retain heat either, so if you're a hot sleeper this construction works in your favour.
